| contents | As IoT and edge inference proliferate,there is a growing need to simultaneously optimize area and delay in lookup-table (LUT)-based multipliers that implement large numbers of low-bitwidth operations in parallel. This paper proposes a hardwareefficientaccurate 4-bit multiplier design for AMD Xilinx 7-series FPGAs using only 11 LUTs and two CARRY4 blocks. By reorganizing the logic functions mapped to the LUTs, the proposed method reduces the LUT count by one compared with the prior 12-LUT design while also shortening the critical path. Evaluation confirms that the circuit attains minimal resource usage and a critical-path delay of 2.750 ns. |
